SEWER-INLET.

SIEGIFIGATIDN forming part of Letters Patent No. 274,465, dated March 27, 1 883.

To all whom it may concern:

Be it known that we, EDWARD Z. COLLINGS, of Camden, in the county ofCamden and State of New Jersey, and CHARLES F. PIKE, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, citizens of the United States, have invented certain new and useful Improvements in Sewer-inlets, of which the following is a specification, reference being bad therein to the accompanying drawings, wherein- Figure l is a transverse vertical section of a sewer and inlet with disinfecting appliances, the latter being represented in elevation. Fig. 1 2 is a like view of modified form of inlet.

Our invention has relation to sewer-inlets, and has for-its object the provision of means for disinfecting the inlet and sewer, and to prevent the escape oi: sewer or other gases therefrom.

Ourinvention accordingly consists of a sewer and inlet, a reservoir or tank in which is placed a disinfectant liquid, and a pipe or connection provided with acock or valve between 2 said reservoir and inlet, whereby a flow of liquid is caused to pass to the inlet and to the sewer to disinfect the same, and provide a seal of like material for the inlet-trap to prevent the passage of sewer-gas therethrough.

Referring to the accompanyingdrawings, A represents an inlet, and B the sewer, of any suitable or desired form, having a connecting pipe or conduit, C, and a trap, a. The latter may be a partition-trap, as shown in Fig. l; or

it may be constructed as shown in Fig. 2, or in any other suitable manner.

1) represents a reservoir located beneath the surface of the pavement, or in a building adjoining the inlet, and is provided with a pipe, E, having a valve or cock, 6. Said pipe is connected to the inlet at e, or at any other suitable or desired point. Through the stopple d of tank I) the disinfectant is passed to till the same when said tank is so located that 5 access is readily obtained thereto. W'hen, however, it is buried beneath the sidewalk, a. pipe is used in lieu of the stopple, said pipe extending up to the surface of the sidewalk, and is provided with a suitable cap or cover.

The cock 6 is. opened to any desired extent to regulate the volume of the flow of disinfectant Application filed August 10, 1882. (No model.)

from reservoir I) to inlet A. As such liquid enters and passes through inlet-chamber A, trap a, and the sewer B, said parts are disinfectedamlrenderedpureand wholesome. Suchliq- 5 uid also forms a disinfecting-seal for the trap a, and sewer-gas or other odors seeking to pass therethrough are at once absorbed and killed or neutralized by such liquid. The cock 6 may be so regulated that the fluid in reser- 6o voir D will continuously flow therefrom in a small stream during the intervals between the successive fillings oi the tank D; or it may be so regulated to pass or flush alarge volume of disinfectantsinto the inlet at certain determined intervals. Such fiushings may he made at stated times, or whenever it is desirable, or when necessitated by the condition of the sewer and inlet.

If desired, the valve 6 may be dispensed with and the pipe E constructed with a bore of a size just sutficient to permit the desired volume of How to pass therethrough.

' What we claim as our invention is- 1. A sewer-inlet provided with a seal, and means, substantially as shown and described, for passing a stream or flow of disinfectingfiuid to said parts, substantially as set forth..

2. A sewer-inlet provided with a trap, in combination with a tank for holding a disin- 8o fectant, and a pipe or connection between said inlet and tank, substantially as shown and de scribed.

25. The combination of inlet A, provided with a trap, a, sewer B, reservoir D, and pipe- 8 connection E between said reservoir and inlet, substantially as shown and described.

4. The combination of inlet A, having trap a, the reservoir 1), adapted to form ad-isinfectaut-holding chamber, and a pipe, E, having a valve, 0, for regulating the flow of disinfecting-liquid to theinlet, substantially as setfort-h.

5. The combination of inlet A, having trap a, and valved pipe E, substantially as set fOIbh. 9 5

In testimony whereof we affix our signatures in presence of two witnesses.
